The five women were snapped from behind for the contest, which is decided by their peers voting online.

And to spice the whole thing up a bit, five men joined in too.

The women can be seen completely naked in a college launderette, on a campus lawn and in their studies.

Gwendoline, an Arabic student, appears to be posing in her room at Sidney Sussex college.

Another girl Amber, who is reading Geography at Trinity Hall, is pictured next to a 'Keep off the grass' sign on college grounds.

And Shelley, from Newnham College, who is reading Chinese, Anglo-Saxon Norse and Celtic, and fellow nudist Pam from Lucy Cavendish college, both appear in non-descript rooms.

The fifth entrant, Natural Sciences student Bella, from Queens' College, is pictured in a college laundry - let's hope she wasn't caught unawares.

One of the entrants, who asked not to be identified, said: "My bum is in it's prime, it's only downhill from here. It was now or never really."

All the women are completely naked, except for Gwendoline, who appears in racy pink knickers with the label out.

The pictures have been posted on student website The Tab alongside five nude male entrants, including one posing in the University Library.

Organisers said all the entrants had "volunteered" their services and they had intentionally run a male competition alongside the women.

But the poll has been slammed by campaigners as "irresponsible".

In a joint statement Anija Dokter from Cambridge Feminist Society, and Lauren Steele, women's officer at the University Student's Union, said: "This is an example of immature, blind and irresponsible behaviour on the part of the Tab editors.

"I sincerely hope they will take responsibility for the harm caused, not only to the women depicted but also to the broader community, for reinforcing sexism and exclusion.

"The Tab should immediately remove the photos, publish an apology and mandate that all future publications cannot include the misuse and appropriation of women's and other minority's bodies."

The Tab declined to comment on the poll but revealed the winners each get entry to the Cambridge Museum of Technology - worth just £2.

The University of Cambridge declined to comment but confirmed they would not be speaking to The Tab about the competition.
